Lightning to USB Camera Adapter and Ipad4
I purchased Lightning to USB Camera Adapter. I need to read ipad4 video files through Lightning to USB Camera Adapter to which a SanDisk MobileMate Duo USB Micro SD card adapter is connected. Exit the error message >> can not use the device >> requires too much energy. So? How can I read the microSD through the Lightning to USB Camera Adapter? Thank you
